Conclusions:
1.

Rehabilitate Angat Dam as soon as possible

2.

Activities concerning DRRM must be given to DRRMC R-3 aslead agency

3.

Enhance capability/preparedness of all sector not only
government entities

44.

Conduct periodic dam-break-drill
dam break drill

55.

This study must have a follow
follow-up
up study

6.

Adopt Japanese dam technologies in Angat dam, Philippines

Filipinos are known for being resilient andGod loving people,people we never stop praying…
